Product description
The optical receivers are intended to convert optical signals into electrical RF signals.
The receivers are dedicated to operate with suitable TERRA wideband SAT IF transmitting system. See manuals of
appropriate devices in www.terraelectronics.com.
The products are intended for indoor usage only.
Safety instructions
Installation of the receiver must be done according IEC60728-11 and national safety standards.
The receiver is powered from low DC voltage, which is not dangerous to life.
Any repairs must be done by a skilled personnel.
To ensure safe operation of the receiver follow these instructions:
Do not connect supply voltage until all cables have been connected correctly.
The receiver shall not be exposed to dripping or splashing water.
Avoid placing the receiver next to central heating components and in areas of high humidity.
If the receiver has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before powering.
The ventilation should not be impeded by covering receiver with items, such as newspapers, table-cloths, curtains.
Avoid looking directly into beam, laser light can cause eye injuries and result in permanent loss of vision.

Optical connections
Note: All optical connectors and adaptors should be cleaned before connecting them.
If optical reception power of the receiver decrease, ber connection should be cleaned and maintained.
Fiber connectors should never be left uncovered.
1. Align the FC type connector key-way (type R) with the receptable key-way.
2. Push rmly to locate the key-ways and then rotate the coupling ring.
3. Do not exceed the minimum bending radius of bers: must be not less 30 mm when connecting optic cable to the system.

Istallation instructions
Read the safety instruction rst.
All unused F type connectors must be terminated with 75 Ω loads.
Mount the receiver in vertical position with optical connector on top.
From top, left and right side leave 10 cm free space.
The receiver must be xed with steel screws Ø 4-5 mm. Screws are not included in a package.
Powering
The receiver can be powered in two ways: from AC/DC adapter through 3.5/1.3 DC connector (pos. 9, Figure 1) or through
RF outputs (pos. 2, 3 Figure 1).
Optical input and RF outputs
The operational optical input level of the receiver is -15...-5 dBm. In this region OLC is working and provides xed RF
output levels. Ensure optical input level in this range.
A direct optical connection cannot be made between the transmitter and the receiver. Use appropriate optical attenuator.
